Teeth names are created by a combination of 4 different characteristics: 1  The jaw where they are located: upper and lower (alternatively the terms maxillary and mandibular can be used) 2  The side of the face: left and right.  The type of tooth: incisor, canine, premolar, and molar.
Vampire bats are members of the New World Leaf-nosed bats, the Phyllostomidae. All three species of living vampire bats occur in South and Central America. Fossils of three other species reveal that several thousand years ago vampire bats were more widespread.
Common vampire bats mate year round, with birth peaks during April and May and in October and November. Most females have one pregnancy per year, although more than one is possible, and single offspring are usual. The gestation period is about seven months, and pups are born with their eyes open.
